IMPROVEMENT I VENTILATORS.

Specification forming part of Letters Patent No. 116,049, dated June 20, 1871.

To all whom it may concern:

Be it known that I, HENRY A. GOUGE, of Brooklyn, in the county of Kings and State of New York, have invented certain Improvements in Ventilating Apparatus, of which the following is a specification:

My invention relates to the combination of a blower operated by steam or other motive power and a Ventilating-tube or liue in such a manner that, when'the said blower is in operation, a jet of air is directed through a small tube into the open lower end of the ventilatin g-tube or line, which will, by its issuing force, induce a current of air int-o the flue from the apartment to be ventilated.

Figure 1 is a front elevation of the apparatus embodying my invention. Fig. 2 is an elevation, showing that side of the apparatus 'which isat the right hand in Fig. 1. Fig. 3 is a vertical section, showing those parts ofthe apparatus which are at the left hand of the line fr a0, drawn vertically upon Fig. 1.

A is the back ofthe apparatus, used, in this case, to sustain the parts, and represents the wall and .oor of an apartment in which the apparatus may be placed. B is the blower, which is operated by th e pulley-crank C through the medium of the cord O over the small pulley E, and should be turned in the direction indicated by the arrow on the pulley-crank O. D is the ventilatingtube or ilue, which is made larger wherever an opening is made into it. F is the weathencap, which, while it permits free egress for the air from the iiue, has a detlector, N, which prevents the entrance of wind, rain, snow, or any effect of a storm. The tube or flue D is provided with a door, G, by which the amount of air taken from the apartment through the opening H is regulated, and in the drawing is shown to be open, and may be closed by means of the card I.

When the blower B is in operation a current of air is forced through the blower-tube J `into the open end of the Ventilating-fine D. Between the tube J and the iue D a space is left, marked K, and into this space K a current of air is induced by means of the issuing force of the jet of air from the tube J. This current and jet, uniting in their ascent, form a partial vacuuin in passing the small tube L, Fig. 3, and thus another current of a-ir enters the flue D through the opening M. The three currents, ascending as one, are made to induce still another current of air from the apartment through the opening H, a partial vacuum being formed by the passage of air behind the open door Gr. The air is ultimately discharged at the weather-cap.

I do not desire to be restricted to the use of one small blower to each Ventilating-liuc, but hold the right, where more than one iiue is used, to make one blower answer for all by conducting a tube, J, from the blower to eachA ue. I claim as my invention- The combination of the blower B a-nd the Ventilating-flue D, and the arrangement of the tube J, substantially as and for the purpose hereinbefore set fort Y HENRY A. GOUGE.
